摘要

本文研究了非对称杂环戊烷衍生物的合成及其构效关系分析。先导化合物5d对转移性三阴性乳腺癌（TNBC）细胞具有强效（IC50 = 0.38±0.05 μM）和选择性（选择性指数：2-9）的生长抑制作用。机制研究表明，5d通过泛素-蛋白酶体途径减弱蛋白酶体降解活性，导致G2/M期细胞周期阻滞，诱导凋亡细胞死亡。

Discovery of New Non-Symmetrical Heterocyclic Pentanoid Derivatives Targeting Metastatic Triple-Negative Breast Cancer

This study describes the synthesis and structure-activity relationship (SAR) analysis of non- symmetrical heterocyclic pentanoid derivative as potential anti-cancer agents. The lead compound, 5d, exhibited potent (IC₅₀ = 0.38 ± 0.05 μM) and selective (Selectivity Index: 2–9) growth inhibitory effects on the metastatic triple-negative breast cancer (TNBC) cells. Mechanistic studies revealed that 5d attenuates proteasomal degradation activity via the ubiquitin-proteasome pathway, leading to G2/M phase cell cycle arrest and the induction of apoptotic cell death.
